1. Scope description
1.1 Introduction
The Schmidt & Bender PM II series scopes are designed to meet the unique
challenges of high precision shooting. Their quality and function make it
possible to achieve exceptional shooting results as well as to fulfill the critical
and demanding needs of official, law enforcement and tactical applications.
Strict observation of the following operating instructions is prerequisite for
successful long-term use.
1.2 Safety instructions
Never look into the sun or into laser light with the scope. This may cause serious
eye injuries. Do not tamper with the scope. Any repairs beyond the
maintenance described in the maintenance manual should only be
performed by Schmidt & Bender or by other specialists authorized by Schmidt
& Bender. Protect the scope against shocks beyond normal use.
Avoid unnecessary long exposure of the scope to direct sunlight; intense and
excessive sun radiation will cause extremely high temperatures inside the tube
which may be detrimental to the scope.
The scope must be properly mounted to the firearm by a qualified specialist.
Perfect mounting is an essential requirement for maximum accuracy and
efficient functioning of the firearm and the scope. Be sure to assume the
proper firing position and keep a correct eye relief in order to obtain an
optimal full field of view and to avoid any injuries due to the recoil of the
weapon.

4.1 Adjusting the image focus with the diopter adjustment of the
eyepiece
The eyepiece provides the adjustment of the reticle focus to the individual
eye diopter. Set the scope to the highest magnification. Rotate the eyepiece
counterclockwise until it stops. Rotate the eyepiece clockwise until you see a
sharp image of the reticle (see Illustr. 3).
Illustr. 3: Diopter adjustment
4.2 Parallax adjustment
The 5-20x50 PMII scope provides parallax compensation with an easily
operable setting wheel
(Illustr. 4), positioned as a third turret opposite the windage adjustment. With
this turret the shooter may easily focus targets at any distance without having
to interrupt his target acquisition.
The parallax adjustment turret is engraved with distance markings. If the
distance to the target is known rotate the turret so that the corresponding
distance marking lines up with the index mark on the saddle.
If the distance to the target is not known set the scope to the highest
magnification and then move the adjustment ring of the parallax
compensation in the direction of the estimated distance until you obtain a

focused image. Now the parallax has been properly adjusted and you may
also read the distance on the turret.
Illustr. 4: Parallax adjustment
4.3 Using the reticle for the distance estimation
The different available reticles offer a variety of possibilities to estimate or
measure important parameters by means of reticle subtensions. This allows the
shooter to place highly precise shots even on large distances by use of the
estimates, the ballistic compensator and the parallax adjustment.
The reticle is in the first focal plane such that the reticle subtensions remain
constant on all magnifications.
Exemplary for the P4F reticle in the first focal plane (see picture below) the
distance “B” of the large tics corresponds to 10cm/100m. The shooter can thus
calculate the distance to a target which size is known by measuring it with
the reticle pattern: If a 10cm sized target fits inbetween two large tics, it is
positioned in a distance of 100m.

For arbitrary object sizes and distances a relation exists according to the
following formula:
𝑑 =
𝑔
𝑎
∗ 100𝑚
Whereas
𝑑 is the distance to the target,
𝑔 is the estimated size of the target,
𝑎 is the size of the target on the reticle pattern.
According to the measured distance, the parallax can be set and the bullet
drop can be compensated by the elevation turret.
Notation of subtensions exemplary for the P4F.
The reticle subtensions for your reticle can be found in the catalog or on the
available datasheets.

5. Point of impact correction
5.1 Using the elevation turret and the windage turret
Elevation turret – Lockable Single Turn Turret with More Tactile Clicks
The elevation turret includes the following features:
 Single turn
 MTC (more tactile click)
 Zero Stop
 Locking function
The elevation turret provides a fine click adjustment value in addition to a
large elevation adjustment. The zero stop function supports the quick
adjustment to the zero position. The zero stop function is determined by an
end stop.
The MTC (more tactile click) elevation turret has an audible "clunk" on every
10th click.
The elevation turret includes a locking function which prevents the
inadvertent adjustment of the turret. To lock the turret, the outer flange with
the engraving must be pushed down in direction of the scope tube until
“LOCKED” appears on the turret (Illustr. 5) To unlock the turret, the outer flange
must be pulled up until the “LOCKED” indicator completely disappears (Illustr.
5).

Windage turret – Single Turn Turret with Zero Stop and Protective Cap
The windage turret includes the following features:
• Single turn
• Zero Stop
• Protective cap
The low profile windage turret is protected against inadvertent adjustment by
a cap. To operate the turret, the cap is rotated counter-clockwise for removal.
(Illustr. 6) The windage turret has one positive "clunk" at the zero position which
provides a "0" reference point.
Illustr. 6: Removing the cap
5.2 Preliminary adjusting and fine adjusting when sighting in
When sighting in the scope for the first time, or re-sighting the scope due to
service or repair, a test shoot for zeroing the scope must be performed on a
100m distance. Therefore, ensure that the parallax is set to the correct value

of 100m and that both elevation and windage turrets are set to “0”. The
double turn turret must be set to the first revolution.
The centering of the target pattern is then performed according to
paragraph 5.3 and 0.
Lock the elevation turret, loosen the two setscrews on the outside diameter
in line with the “LOCKED” indicator using an Allen key (see Illustr. 7). Unlock
the turret by pulling up the outer flange and turn the turret until the
engraved “0” is indicated by the triangle on the saddle. Lock the elevation
turret by pushing down the outer flange with the engraving and tighten the
two setscrews with an Allen key.
To zero the windage turret, removed the turret cap and loosen the two
setscrews turn the turret to zero. Then retighten the screw and screw the
turret cap cover back onto the turret.
 The turrets are secured by an additional third slotted screw which should
only be removed when completely replacing the turret due to damage.
 The turret clicks can still be felt and heard when the screws are unlocked.
This has no impact on the process of zeroing as the thread piece does not
move while the setscrews are loose.

5.3 Elevation adjustment
Depending on the configuration, the point of impact is moved by either
0.1mrad (1cm on 100m) or ¼ MOA with every click. A too low point of impact
is corrected by rotating the elevation turret counter-clockwise (see Illustr. 8),
a too high point of impact by rotating the elevation turret clockwise.
 For clockwise rotating turrets this relation is opposite!

5.4 Windage adjustment
Depending on the configuration, the point of impact is moved by either
0.1mrad (1cm on 100m) or ¼ MOA. A too far left point of impact is corrected
by rotating the windage turret counter-clockwise, a too far right point of
impact is corrected by rotating the turret clockwise (see Illustr. 9).
 For clockwise rotating turrets this relation is opposite!

6. Maintenance
6.1 Using the scope covers
To protect the scope and its lenses against adverse environmental conditions
like sand, dust, rain, snow, etc., the protective flip-up caps of objective and
eyepiece should be closed after every use of the scope. Before shooting,
make sure that the caps are open.
6.2 Care and maintenance
Schmidt & Bender PM II scopes do not require any special maintenance. All
metal parts have a hard anodized surface that is extremely scratch-resistant
and easy to care for.
For cleaning outer surfaces, use a clean and, if necessary, a slightly damp
cloth.
For cleaning the optics use the included Schmidt & Bender cleaning kit.
Before wiping the optic’s surfaces, use a dry brush to remove coarse dirt or
dust particles. Slight impurities may then be wiped off using an optic’s
cleaning cloth.
Breathe onto the optic’s surfaces before cleaning them, this helps with the
cleaning process. Excessive dirt may be removed using the cleaning liquid
included in the cleaning kit.
Avoid dry rubbing on the outside optical surfaces, this may harm the precious
coatings.
6.3 Storage temperature
The approved temperature range for the storage of the scope is from -55°C
to 70°C.
